The one where Rassmann was on another boat entirely when he fell off.
On March 13, 1969, Rassmann, a Green Beret, was traveling down the Bay Hap river in a boat behind Kerrys when both were ambushed by exploding land mines and enemy fire coming from the shore. Kerry was hit in the arm, while a mine blew Rassmanns boat out of the water. With enemy fire coming from both sides of the river and swift boats evacuating from the area, Kerrys crew chose to turn their boat toward the ambush to save Rassmann.
